4. Engage Engage with Clink! Read-Aloud and Explore with Wind-Up Robots
Clink read by Kevin- link
What is a Spring?
Can you name examples of springs
Are all springs metal?
Why doesn’t anyone want to buy Clink? (He
is an old toy.)
Why does the boy think Clink is perfect?
How do you think Clink works? What are his parts?
Are there any clues in the text or illustrations?
In this lesson students will observe the motion of a wind up toy. As you read ask the above questions.
Rubber band can be a spring because it stretches.
Students are also engaged in the science and engineering practice of constructing explanations and designing solutions

5. Explore Questions- Give each pair of students a wind up robot.
How do you get the toy to move?
How do you think the number of times you wind it up affect the distance the toy travels?
How could we find out?
What would be a good way to collect the data?
What do you think is inside the toy?
What makes it go?
How can we find out?
Give each pair of students a wind up robot.
Have students observe how it moves.
To collect data give students the wind it up student page, ruler or tape measure.
Give students time to explore and collect, compare and share data.
Use the questions on page 103 to guide the discussion on the exploration.
Safety
Teacher will need a protective glove and screwdriver to disassemble the toy
Mathematics – Connecting to common core
Measurement and data-3MD.3, 3MD4

6. Explain Making machines with springs read aloud. Turn & Talk:
What is a spring?
Where are springs used?
What forces do you need to make a spring change shape?
Tell students they are going to find out how the spring inside the robot makes it move.
Read aloud pages 4-7
Do the activites on pages 8-11.
Forces- two pulling forces

7. What is a spring?
Coil springs
Springs are elastic bodies (generally metal) that can be twisted, pulled, or stretched by some force. They can return to their original shape when the force is released.
In other words it is also termed as a resilient member.
When a spring is compressed or stretched (force applied), then it gets a change in length.
i.e., Force or Load α Length of Spring. applied), then it gets a change in length.
Clock or spiral spring

8. Common uses of Springs
A sloping surface, such as a ramp. An inclined plane can be used to alter the effort and distance involved in doing work, such as lifting loads. The trade-off is that an object must be moved a longer distance than if it was lifted straight up, but less force is needed. You can use this machine to move an object to a lower or higher place.  Inclined planes make the work of moving things easier.  You would need less energy and force to move objects with an inclined plane.
